After this emergency shutdown I was able to reboot the system normally. The dCache pools also came up fine, even though the running jobs were not able to recover (connections stayed in a hanging state with "no movers found" state marked in the active transfers page).

15. 12. 2008 Again t3fs03 problems - OS patching

Again, the pools on t3fs03 went offline and the system was in a strange state. The system log pointed again to the marvell issue. I decided to immediately patch the system. First I again needed to forcefully shut the system down and reboot.
